What Weeroc does
Weeroc is a fabless semiconductor company founded in 2012 as a spin-off from CNRS/IN2P3, France's National Institute for Nuclear Physics and Particle Physics. Headquartered in Villebon-sur-Yvette (Paris suburbs), the company employs 1-10 people and has operated as self-financed since inception, generating revenue through customer projects without external venture capital. Its core competency is the design of radiation-hardened, space-grade analog and mixed-signal integrated circuits — specifically photodetector read-out ASICs — with performance characteristics such as sub-20ps FWHM timing resolution and 300MHz per-channel photon counting. The product portfolio is organized around the GenerIC family of pin-to-pin compatible space-grade ASICs (Liroc, Radioroc, Poproc, Psiroc, Temporoc), supported by the Conan space-grade power controller, a range of photodetector read-out modules (PoPico, RaPico, LiPico, Spectrocam) integrating CERN PicoTDC time-to-digital conversion, and turnkey IC design and system design services spanning concept through industrialization.
The company serves four primary verticals: scientific instrumentation (CERN, CEA, INAF, CTA/ASTRI Cherenkov telescopes), aerospace and space-grade electronics (Airbus, NASA JPL, CNES for satellite and LIDAR applications), medical imaging (EIC Pathfinder RETIMAGER PET systems), and nuclear safety and decommissioning (Damavan Imaging, Andra). Commercial silicon is fabricated through foundry partnerships with TSMC, X-Fab, STMicroelectronics, Microchip, and AMS, enabling access to processes from low-power CMOS to BiCMOS SiGe and space-qualified rad-hard technologies. Weeroc distributes off-the-shelf products exclusively worldwide through CAEN, while custom ASIC and system design services are engaged directly via the company website on a quote-based, multi-year contract basis. Customers include both enterprise accounts (Airbus, Damavan Imaging) and government and research institutions (NASA, CNES, CERN, CEA, Andra, INAF). Certifications include ISO 9001 with adherence to aerospace standards.
